MAX78615+PPM
Isolated Energy Measurement Processor
for Polyphase Monitoring Systems
General Description
The MAX78615+PPM is part of an isolated energy mea-
surement processor (EMP) chipset for polyphase power
monitoring systems. It is designed for real-time monitor-
ing for a variety of typical three-phase configurations in
industrial applications.
The device provides flexible sensor configuration for up
to three MAX78700s or MAX71071s that provide up to
six isolated analog inputs for interfacing to voltage and
current sensors. Scaled voltages from the sensors are
fed to the isolated front-end utilizing a high-resolution
delta-sigma converter. Supported current sensors include
resistive shunts and current transformers (CTs).
An embedded 24-bit measurement processor and firm-
ware perform all necessary computations and data for-
matting for accurate reporting to the host. With integrated
flash memory for storing nonvolatile calibration coefficients
and device configuration settings, the MAX78615+PPM
can be a completely autonomous solution.
The MAX78615+PPM is designed to interface to the host
processor through the UART, SPI, or I2C interfaces, and
is available in a 24-pin TQFN package.
